We first look at the possibility that irradiation of the disc is
responsible for all the issues highlighted in the previous section.
Irradiation of the inner disc changes its derived temperature and
radius compared to that derived from fitting purely gravitational
energy release models of the disc (GDP08). Similarly, irradiation of
the outer disc can also increase the optical/UV emission from that
expected from an unilluminated disc ([1]};GDP09)
